1

Which part of the pharynx lies posterior to the oral cavity?

Oropharynx

2

Is the hard palate anterior or posterior?

Anterior to soft palate

3

Which structures form the hard palate?

Palatine process of the maxilla

Palatine bone

4

What are three muscles which make up the floor of the mouth?

Mylohyoid

Geniohyoid

Anterior belly of digastric muscle

5

Which bone is found inferior to the oral cavity and floats freely?

Hyoid bone

6

Which surface of the tongue is the underside?

Ventral surface

7

Which veins can be seen on the ventral surface of the tongue?

Lingual veins

8

Which folds are found under the tongue?

Sublingual folds

9

What are the three pairs of major salivary glands?

Parotid glands

Sublingual glands

Submandibular glands

10

Which salivary gland is found just anterior and inferior to the ear?

Parotid gland

11

Which duct drains the parotid gland?

Where does it emerge?

Parotid duct

Buccal mucosa

12

Which salivary gland is found on the floor of the mouth?

Sublingual gland

13

Where do the sublingual glands drain?

Sublingual folds

14

What is found between the sublingual folds?

What drains here?

Sublingual caruncle

Submandibular glands via the submandibular ducts, which is quite confusing

15

What is the structure which links the ventral surface of the tongue to the floor of the mouth?

Frenulum

16

Which muscle of mastication is the parotid gland superficial to?

Masseter

17

Which cranial nerves innervate the

a) parotid gland

b) submandibular and sublingual glands?

a) CN IX - glossopharyngeal nerve

b) CN VII - facial nerve

18

Which salivary glands are innervated by

a) CN VII

b) CN IX?

a) Submandibular and sublingual glands (remember that facial nerve also does the lacrimal glands)

b) Parotid glands

19

How does CN VII supply the submandibular and sublingual glands?

What does it hitch a ride with?

Chorda tympani

CN V- lingual nerve branch

20

Where does CN IX synapse before supplying the parotid gland?

Otic ganglion

21

Which kind of muscle is the tongue made up of?

Skeletal muscle

22

Which cranial nerves supply the general sensory fibres for:

a) anterior 2/3rds of tongue

b) posterior 1/3rd?

a) CN V3

b) CN IX

23

Which structure in the tongue did the thyroid gland descend through during development?

Thyroglossal duct

via the foramen caecum

24

What is the foramen caecum?

Hole in the tongue where the thyroid descended during development

25

Through which tube did the thyroid gland descend during development?

Thyroglossal duct

26

Which direction does the larynx move in during swallowing?

UP

then DOWN

27

Which direction do the thyroid gland and its remnants move during swallowing?

Why?

UP then DOWN

They're attached to the larynx

28

What are the four intrinsic muscles of the tongue?

Palatoglossus

Styloglossus

Hyoglossus

Genioglossus

29

What is the function of the extrinsic muscles of the tongue?

Change position of tongue during

mastication

swallowing

speech

30

What is the motor supply to the extrinsic muscles of the tongue?

What is the exception?

CN XII - hypoglossal nerve

Palatoglossus is innervated by CN VII
